Class LocalSymbolKey

Object

gudusoft.gsqlparser.dlineage.symbol.LocalSymbolKey

public final class LocalSymbolKey
extends Object

The key of a local symbol of the lineage model: a variable, a cursor, a declared type, a trigger correlation name or a table variable, by the scope it is declared in and its name as written.

The scope is the declaring routine's frozen scope (see LocalScopes), or an overload pool's (IdentityScope), or null at top level. The name is keyed by the analysis's identifier rules under the object type of its namespace. Declared locals (variables, cursors, declared types, table variables) share one namespace, as a cursor and a variable of one name are one name in a declare section; a trigger's correlation names are another.
